VALVE.

Specification of Letters Patent.

Patented Nov. 5, 1912.

Application filed November 9, 1910. Serial No. 591,520.

To all whom it may concern:

Be it known that I, LABS L. 0m, a subject of the King of Norway,residing at San Pedro, in the county of Los Angeles, State ofCalifornia, have invented a new and useful Valve, of which the followingis a specification.

This invention relates to a valve particularly adapted for use in theconnection of tanks for compressed gases or air with service pipes orwith recharging pipes. In such cases, it is desirable to be able to makea number of alternative connections, for example, to connect the tank toone or both of a plurality of service connections or to connect the tankto a recharging connection, and one object of the invention is toprovide a simple and eflicient valve whereby such different connectionsmay be made.

Another object of the invention is to provide means whereby theregulation of the flow of gas or air may be determined by one of themembers of the valve and the opening and shutting of the connection maybe controlled by another of said members, whereby any adjustment whichhas been made by the first named member of the valve may be retainedindefinitely, thereby saving considerable time and trouble in theoperation.

Another object of the invention is to provide a Valve particularlyadapted for high pressure gas work inwhich the liability of leakage dueto the high pressure is avoided.

Another object of the invention is to provide improved means forstraining the gas as it comes from the tank. This is of specialimportance in connection with acetylene tanks, wherein acetone is usedas an absorbent medium, the straining preventing the blowing off of suchliquid from the tank as well as prevent-ing the passage of any sediment.

Other objects of the invention will appear hereinafter.

The accompanying drawings illustrate the invention, and referringthereto:

Figure 1 is a side elevation ofthe valve with the connections forrecharging. Fig. 2 is a section on line 02 -02 in Fig. 1. Fig. 3 is asection on line 119 -16 in Fig. 2. Fig. 4

is a view similar to Fig.3, showing the connections for double service.Fig. 5 is a perspective ofthe strainer. .Fig. .6 is a side elevation ofthe valve with the tank to which it .is attached and double serviceconnections leading therefrom. I

The valve comprises a body or casingl formed with extensions orprojections 4, 5 and 6 for receiving the several connections and withother extensions 7, 8 and 9 for receiving the movable valve members forcontrolling the passage of fluid through such connections.

Extension 4 from the casing 1 may be formed with a screw member 10adapted to screw into a corresponding opening in a tank 11. The casing 1is formed with a passage 2 extending in this casingextension 4 andformed with a seat 12 for a valve '13 screwing through the oppositeprojection 7 on the case, said valve 13 extending through a stuffing box14 and being provided with a wrench hold 15 at its upper end. Saidpassage 2 extends to a strainer chamber 17 in which is secured astrainer 18., Said strainer preferably consists of wire gauze disks 20,21, with an intervening disk 22 of suitable porous material, preferablyasbestos, and the strainer is held in place by a screw bushing 23screwing into the lower end of the casing extension 4.

The casing extension 5 is formed with screw means 25 adapted to receivea union indicated at 26 for connection of a tubular member 27 adaptedfor recharging connections. The inner end of said tubular member 27 isformed with a head 29 constituting the inner member of the union nestedwith the nipple 24. and clamped by the collar member 26 of the union, sothat the tapered inner end of said head 29. engages with a correspondingtapered recess or socket 80 in the outer end of the extension 5. Apassage 31 extends in said casing 'to the said socket 30, this passagebeing formed with a seat 32 for a valve 33 screwing in the projection 8of the casing and extending through a stuffing box 34 and provided atits upper end with a wrench hold 35. The casing extension 5 is alsoformed with. a nipple 24,

adapted to receive a flexible tube indicated at 28, in Figs. 4 and 6,this nipple extending within the recess 30, and within a recess 38 inhead 29.

The projection 6 from the casing serves to receive a nipple member 36which screws thereinto and is adapted to receive suitable connectionssuch as flexible hose 37 for connection to service or other pipes, thesocket- 39 into which the member 36 screws being connected with apassage 40 having a seat 41 with which engages a valve 42 screwing inthe projection 9 of the casing and extending through a stufiing box 43and provided at its outer end with a wrench hold 44. The axes of thepassages 2, 31 and 40 extend in different planes and in differentdirections, so that the valves 13, 33 and 42 do not interfere with oneanother in their operation. The said valves are shown as extendingmutually at right angles to one another, this construction providing themost convenient connect-ions. Said valves 13, 33 and 42 are preferablypin valves, the

passages 2, 31 and 40 being cylindrical and slightly larger than thepins of the valves, so as to allow passage of gas alongside said pins,and the said passages being bored in the integral casting'or body 1 insuch manner that they intersect one another and communicate at thepoints of intersection. The said cylindrical passages have their axes indifferent planes, so that the valve pins in the several passages extendpast one another without interference, each cylindrical passage howevercutting through the wall of each of the other cylindrical passages at apoint of intersection so as to permit passage of fluid between theseveral passages.

The valve is capable of numerous applications, for example, as shown inFig. 6, the valve may be connected to the tank 11, said tank being, forexample, an acetylene gas tank used for an automobile lighting system.The tubular connection is here shown as connected by the nipple 24 andhose 28 to an automobile lamp 46 and the nipple 36 is shown asconnectedby hose 37 to an automobile lamp 47, said lamps 46 and 47being, for-example, forward and rear lamps. The union 26 is in this caseremoved, said union being, for example, left on the recharging pipe 27to which it is attached. The valve 13 here serves as a master valve, theopening thereof serving to admit the gas to the inner chamber 2, whenceit may flow to either or both of the pipes 37 or 28 according to thesubsidiary control by valves 33, 42. Assuming that the master valve isopen, the valves 33 and 42 may be adjusted so as to regulate theintensity of the forward and rear lamps separately and this regulationhaving once been effected, the lamps may be turned on andofi'simultaneously by the master valve 13 without interfering with suchregulation,

so that whenever such master valve is opened, the lamps 46 and 47 willburn with the intensity for which they have been previously regulated.On the other hand if it is desired to use the valve in recharging thetank 11, a tubular connection, indicated at 27 is connected by union 26,said union 26 leading from the pipe line or source of compressed gas tothe socket 30 of the valve, the valve 42 is closed and valves 13 and 33are opened, one of said valves being opened only partially so as toretard inflow of gas as much as may be desirable. The valve body 1 beingintegral with the several valve portions, rigidly and hermeticallyconnected, there is no liability of leakage such as occurs where aplurality of valves are connected by means of unions.

What I claim is:
